| 摘 要： | 用一维非平衡辐射输运程序和实验提供的黑腔辐射流，对CH薄膜靶的辐射烧蚀进行了数值模拟计算。计算结果表明，非平衡的黑腔辐射场对CH薄膜靶辐射烧蚀的影响十分明显。出靶外界面的辐射流总强度、等效辐射温度随时间变化、400eV光子出界面延迟时间随靶厚度变化规律等方面的数值模拟结果与实验结果基本符合。

| Abstract: | The radiation ablation experiments of CH foils are simulated using the experiment radiation flow in the hohlraum by 1 D radiation transfer code RDMG. The results of simulation show that influence of Non LTE radiation source on the ablation of CH foil is very obvious. The results of simulation and experiment including radiation flow total intensity and the variation of radiation temperature with time at the rear of CH foil, as well as the time delay of 400eV photon arriving at the rear of CH foil are consistent basically. |
